The Hud finds the table window based on the tournament name given in the hand histories. If there is a difference between the two then it won't be found automatically. As long as they match there should be no problem.
Please enable logging (Configure > Options) and restart PT4.
Play one of these tournaments and take a screenshot
of the table window. Attach it to a Support Ticket
along with the hand history file for the tournament and the PokerTracker4.log file from C:\Users\yourname\AppData\Local\PokerTracker 4\ (which you can access from the PT4 File menu) so that we can see what the difference is for these tournaments.
